sizeof (long) == sizeof (void *) == 8 on alpha.  And no, it's not done as far
as I can say since my system wouldn't work.  Afaik, the sizes of types should
be same on itanium and alpha, unless they did something strange.

Alpha adds the extra benefit of fun stuff with alignment.  And even then
GTK+/GNOME manages to work.  So I would say it's pretty 64bit clean.
